The Problem

Underground water tanks were originally specified under a decking area at the rear of each townhouse in this narrow and sloping Howick development.

Due to the volume required and the size of the excavation needed, this design impinged on the foundation and as such was going to require block wall reinforcing. This was a costly and time-consuming solution.

The Solution

Walker Omes approached Stormwater Systems about coming up with an alternative solution. Our design team reviewed the plans, and despite the narrow and sloping site, they were confident that the modular Aquacomb system would be a suitable solution, given there was enough room in the concrete slab for each site.

Using our 250L Aquacomb pods, we designed a plan that fits within the slab layout without interfering with any internal pipework or reinforcing areas and also met the council requirements. This not only saved considerable time and money but allowed for a water reuse pump placement to be moved away from the outdoor area, saving the client from the need to reduce the living area footprint.

The combined detention and reuse system installed in the foundation slab of this 6-unit development is made up of 66 350L Aquacomb pods, holding 16,500L of water. Each of the 17 downpipes feeding this system has a WaterSmart Leaf Diverter installed to minimise debris
entering the system.
